System, method and apparatus for deploying a data resource within a threaded pipe coupling

ABSTRACT

A data resource specific to a pipe coupling centrally positioned within the coupling, intermediate the coupling ends. Multiple couplings are employed to connect together a string of well pipe. The data resource is adapted to be deployed at the coupling center in the space formed between the abutting ends of pipe made up into the coupling. The data resource provides information regarding the physical characteristics and locations of the coupling, the attached string pipe or the environment within which the coupling is disposed. The data resource may be a read-only component or it may be a readable and writeable component. The resource communicates with an instrument movable through the pipe and coupling. The data resource may be removably positioned at the center of the coupling or it may be permanently cemented in place. The data resource may take on the form of an annular ring with a crushable structure and suitable recesses for holding a data resource module. A circular communication antenna may be carried in the ring. A preferred form of the data resource is an externally threaded Teflon® ring equipped with axially extending resilient fingers. The resilient fingers are deformable upon engagement with the rotating ends of the pipe sections so that advancing the pipe sections beyond their optimum depth into the coupling deforms the fingers without rotating and thus displacing the ring. The body of the ring remains in the gap between the pipe and where it is protected from crushing.

More particularly, the present invention relates to asystem, method and apparatus for deploying a data resource in the formof electronically accessible information into the central area within athreaded pipe coupling intermediate the opposed ends of pipe threadedinto the ends of the coupling.

As used herein, the terms “data resource” is intended to include adevice or composition of matter or an electrical state of a device orcomposition of matter or the organization or presentation ofelectronically transmittable data.

2. Brief Description of the Setting of the Invention

Pipe of different sizes and types is required to drill and complete oiland gas wells. The pipe is made in a large variety of metallurgies andend connection designs. When used in drilling or constructing a well,the correct size pipe with the correct metallurgy and appropriate endconnection must be employed at each of several different phases of theconstruction and completion of the well. During construction of thewell, it may be necessary to acquire or confirm information about thewell pipe. After the well is constructed, it is often necessary tosecure information about the pipe or to determine the location of asubsurface tool or instrument relative to a specific part of the stringof well pipe. For example, in this latter regard, it may be necessary toknow how far an instrument or tool, or the end of a smaller pipe stringhas traveled down through a string of well pipe. The instrument or toolmay be used, for example, to trigger a perforating gun at a desiredsubsurface location.

Pipe is customarily marked on its outer surfaces with visual informationabout the metallurgy and size of the pipe. External markings may alsoprovide information about the type of end connector on the pipe. Evenwhen external markings are present however, pipe used in wellconstruction is usually manually reexamined and remeasured in the fieldbefore being put into use to ensure that the correct pipe in the correctamount is being used. Field measurements are typically performed using ameasuring tape, gages and other length or dimensional measuring devices.These manual inspections or measurements of pipe in the field are timeconsuming, tedious and highly subject error.

A common method for placing an instrument or tool at a precisesubsurface location within a sting of well pipe is to lower the deviceinto the well at the end of a wireline while measuring the amount ofwireline dispensed. When a given length of the wireline has beendispensed, the device is presumed to be at the subsurface locationcorresponding to the measured length of dispensed line.

When the position of a subsurface device is determined by measuring theamount of line that has been deployed to suspend the device in the well,variables such as well temperature and the associated line stretch mustbe calculated to correct the reading at the well surface. In wells thatare deep, for example 15,000 feet or more, the line stretch may besubstantial, causing the measurement to be mistaken by an unacceptableamount. The line measurement technique is also susceptible to humanerror in reading and calibration of the measuring instrument.

Another technique used to determine the location of a device within awell is to use an instrument that detects the passage of pipeconnections as the device is lowered through the string of pipe. If eachsection of pipe is substantially the same length, the approximate depthof the device can be determined by multiplying the length of the pipesection by the number of connections traversed. The equipment requiredto implement this technique is relatively expensive and the accuracy canvary when the pipe sections are not of the same depth or the makeup intothe coupling varies from connection to connection.

It has also been suggested to position a carrier having a data resourcewithin a protected central grooved area of a coupling between two pinends. The data resource is employed for communicating with aninterrogating instrument lowered into the pipe string containing thecoupling. The specific form of the carrier holding the data resource inthis earlier design is subject to damage from engagement with the pipeends during the coupling and pipe makeup process.

There are various other techniques available to more precisely locate asubsurface device but these techniques can also be expensive and timeconsuming to employ.

A primary object of the present invention is to deploy a data resourcewithin a protected area of a threaded coupling in a novel manner thatprotects the data resource and permits it to communicate with aninstrument temporarily positioned within the coupling.

Still another object of the present invention is to provide a novelcontainment ring for deploying a data resource within a threadedcoupling wherein the ring is equipped with a crushable structure thataccommodates limited deformation of the ring by the ends of the pipeconnecting into the coupling. A related object of the present inventionis to provide a crushable structure in a containment ring that does notdeform into the central opening through the pipe-to-coupling connection.

Another object of the present invention is to provide a data resourcethat is cemented or otherwise securely anchored in the spaceintermediate the ends of two pipe sections threadably engaged to acoupling.

Yet another object of the present invention is to provide a dataresource within a threaded pipe coupling whereby the data resource isprotected from mechanical damage from engagement with the end of a pipethreadably engaged within the coupling.

It is also an object of the present invention to mount a data resourcewithin a threaded pipe coupling whereby the rotating advance of athreaded pipe being properly threaded into the coupling cannot damage ordisplace the data resource.

A general object of the present invention is to deploy a data resourcewithin a pipe coupling whereby, the resource is protected fromdistortion or mechanical damage caused by the advancement of the pipeends to their maximum permitted penetration tolerance within thecoupling.

An object of the present invention is to provide a carrier for a dataresource that will contact the ends of the pipe in a coupling tostabilize the carrier and resist its displacement by flow of fluidsthrough the pipe while simultaneously protecting the data resource fromover-penetration of the pipe ends into the coupling.

BRIEF SUMMARY OF THE INVENTION

A preferred form of the data resource of the present invention is thatof an annular containment ring having threads along its outercircumferential surface that are adapted to engage with the internalthreads formed in a coupling. Deformable fingers extend axially awayfrom the ends of the ring toward the associated coupling face. The ringis positioned within the coupling by engaging the ring threads with thecoupling threads and rotating the ring until it is centralized at themidpoint of the coupling. The total axial length of the ring, includingthe extended fingers, is equal to the optimum desired end spacingbetween the end faces of the threaded pipe ends or “pins,” engaged inthe coupling. Penetration of a pin deeper than its optimal depth deformsthe fingers without displacing or damaging the ring or the data resourceassociated with the ring.

The containment ring carries a microchip or other communication devicewithin a protective receptacle formed in the ring body, or if desired,the communication device may comprise the ring itself The data resourceassociated with the ring may, for example, be a passive electroniccircuit, a magnetically imprinted medium or other communicating device.If desired, the communicating component or “module” may be anindependently powered component. The data resource may transmit datapursuant to its own internal control and/or may transmit only inresponse to interrogation from a remote instrument. The energy fortransmitting the data from the data resource to the inquiring instrumentmay be supplied by the inquiring instrument and/or may be a part of thedata module. If desired, the data in the data resource and/or theoperation of the data resource may be altered by separate instrument.

A modified form of the data resource may be provided by cementing and/orotherwise rigidly securing the module acting as the data resourcedirectly to the central area of the coupling.

The foregoing objects, features and advantages of the present invention,as well as others, will be more readily apparent and appreciated fromthe following drawings, specification and claims.

DESCRIPTION OF THE ILLUSTRATED EMBODIMENTS

FIG. 1 illustrates a system of the present invention indicated generallyat S. The system S includes pipe segments or “joints” P1-P5 connectedtogether by couplings C1-C4 to form a string of pipe that extends downinto the earth for extracting minerals or for other purposes. Each ofthe couplings C1-C4 is equipped with a data resource D1-D4 that containsinformation specific to the coupling with which it is associated. Thus,D1 may contain information indicating that it is associated with aspecific coupling C1 or that it is connecting pipe sections P1 and P2 orthat it occupies a specific location within the string or is located ata given distance below the well surface. Additionally, informationregarding the type of coupling, the type of pipe, the type of endconnection, the metallurgy of the components connecting the well stringtogether, as well as other information, may be contained within the dataresource D1-D4.

The data resources D1-D4 communicate with an instrument I suspended inthe string of pipe by an electric wire line EWL. A display device DDcommunicates through the electric wire line EWL with the instrument I todisplay the information obtained by the instrument I from the dataresource. If desired, the instrument I may communicate with the dataresource and augment or alter the information contained in the resource.Additionally, the power for driving the data resources D1-D4 may beprovided by the instrument I or, if desired, may be contained internallywithin each of the data resources D1-D4.

The present invention is directed to the methods and means for affixingthe data resources within the coupling whereby each data resource isprotected during the assembly of the pipe sections into the coupling andwhereby the data resource is effectively able to communicate with theinstrument I from its deployed position within the coupling. Placementof a data resource within a coupling, the specific information containedin the data resource and the process of communicating with theindividual data resource elements are not, per se, a part of the presentinvention.

The data resource components D1-D4 are configured to occupy the centralarea of an internally threaded coupling, such as an API eight round orbuttress coupling. In certain configurations, the data resource takes onthe form of a containment ring that is dimensioned to fit between theends of the pipe engaged in either end of the coupling. The internalclearance through the containment ring is optimally designed to be thesame as that of the pipe engaged in the coupling to minimize turbulentflow of well fluids through the pipe-to-coupling connection.

The system of the present invention comprises a string of pipe securedtogether by couplings equipped with the data resource of the presentinvention. The method of the present invention comprises the use ofspecially configured containment rings to contain and protect the dataresource element by providing a controlled crushing of the containmentring.

A preferred form of the present invention, embodied as a castle topcontainment ring is indicated generally at 10 in FIG. 1A. The ring 10 isdisposed between the ends 11 and 12 of externally threaded pipes 13 and14, respectively. The pin of the pipe 13 is equipped with threads 16formed along the external surface of the pipe adjacent the end 11.Similarly threads 17 are formed on the external end surface of the pinof the pipe 14. A coupling 18 is provided with internal threads 19 thatengage the threads 16 and 17 and secure the two pipes 13 and 14together.

As may be seen by joint reference to FIGS. 1A, 1B, and 2, two radialbores 20 extend through the retention ring 10 to be employed with aplacement tool (not illustrated) for threading the retention ringthrough the coupling to the exact center of the coupling into theposition illustrated in FIGS. 1A and 1B. A receptacle 21 indicated inbroken lines along the outer surface of the retention ring 10 receives adata communication component or “data module” 22 also depicted in brokenlines. The module 22 may be a miniature transmitter/receiver or someform of active or passive recording medium that carries specificinformation relative to the coupling 18 and its associated environment.The module 22 connects electrically with a loop antenna 23 indicated inbroken lines carried in a circumferential groove 24 formed along theexternal surface of a ring body 25.

The containment ring 10 is provided with deformable fingers 26 and 27that extend axially away from the central ring body 25. The containmentring 25 is illustrated coaxially deployed at the center of the coupling18 where it is held in position by threads 28 formed along the externalcircumferential surface of the ring body. The threads 28 mate with theinternal threads 19 of the coupling to retain the body 25 at the centerof the coupling 18.

As may be seen by joint reference to FIGS. 1A-4, the module 22 and theantenna 23 are safely protected within the body 25 of the containmentring 10. The flexible fingers 26 and 27 assist in supporting the body 25centrally within the coupling 18 between the ends of the pipe engaged inthe coupling while simultaneously accommodating the rotating, crushingmovement exerted on the ring assembly 10 by the advance of the pipesinto the coupling.

The coupling 18 and threaded ends of pipes 13 and 14 illustrated in FIG.1 are exemplary of an American Petroleum Institute (API) threaded andcoupled connection equipped with eight round threads. The pipes 13 and14 are illustrated “made up,” i.e. threadably engaged, to an acceptableAPI position within the coupling 18.

The recommended API procedure for securing together eight round threadsrequires that the ends 11 and 12 of the pipe must be made up into thecoupling within a defined distance from the adjacent end of the “J”dimension of the coupling. In many API sizes, the J dimension is thecenter 1″ space of the coupling and the tolerance for the pipe end is±¼″ from the end of the J dimension. Thus, when properly made up withthe API coupling, the pipe ends 11 and 12 may not be closer togetherthan ½″ and may not be spaced further apart than 1½″.

The retention ring 10 is dimensioned so that the space occupied by thering body 25 and the fully deflected fingers 26 and 27 (caused byadvancement of the pins into the box) will occupy the minimum allowedspace at an acceptable API approved connection position. With both pinsmade up into their maximum permitted penetrating position, the remainingspace between the two pipe ends for a connection that is within the APIspecification is ½″. Accordingly, the retention ring body 25 and thefingers 26 and 27 are sized to allow the fingers to be fully deflectedagainst the ring body 25 within a space of ½″ between the ends of thepipe. Thus, it will be appreciated that the selection of component sizesfor pipe having the described API makeup tolerance is such that thecollapsed or crushed form of the retention ring is equal to or less thanan axial length of ½″. It will be understood that it may be desirable toprovide a retention ring having a significantly smaller collapseddimension to protect the data resource even in connections that are madeup beyond the permitted API tolerance.

FIG. 1B illustrates the data resource 10 positioned between the two pipeends 11 and 12 after the pipe ends have penetrated the coupling 18beyond the end limits of the J dimension. The fingers 27 engaging thepipe end 11 are seen to be compressed further against the ring body 25than the fingers 26. The difference is due to the greater penetration ofthe pipe 13 into the coupling.

As may be noted by reference to FIG. 1B, the fingers 26 and 27 arepointing in different directions. The pipes 13 and 14 are rotated inopposite directions during their make up thus accounting for thedifferent direction of deflection of the fingers. It may also beappreciated by reference to FIG. 1B that the lengths of the fingers 26and 27 are such that their crests do not engage the base of an adjacentfinger when the fingers are fully deflected against the ring body 25.This feature permits the collapsed form of the retention ring to occupya smaller axial dimension within the coupling.

The containment ring 10 may be constructed of a polymer ofpolytetrafluoroethylene, such as Teflon® or other suitable material. Thematerial of the ring 10 is preferably such that it may withstand thewell environment and does not hamper the electronic transfer of data toand from the data module. The containment ring may be machined or castfrom a suitable material. The data module 22 may be cemented into thereceptacle 21 or otherwise suitably held in place during the positioningof the ring within the coupling. The loop antenna 23 may be routedaround the circular bores 20 to keep the bore filly open to receive thedrive pins (not illustrated) from the placement tool used to positionthe ring within the coupling.

Throughout the description that follows, similar reference charactersdepict similar or equivalent structure and compositions in the variousembodiments. The equivalent or similar structures for differentembodiments are identified by reference characters that differ from eachother by a magnitude of 100. Unless otherwise noted, the construction,function and use of corresponding components are similar or equivalentin each of the embodiments.

FIG. 5 illustrates a modified form of the containment ring indicatedgenerally at 110. The ring 110 includes a circumferentially extendingrecess 121 for holding a data module. The ring 110 is equipped withstandoff rims 126 and 127 on either side of circumferentially disposedthreads 128. Multiple, radially extending bores 126 a and 127 a extendthrough the rims 126 and 127, respectively, to provide crush space forthe containment ring 110. A central groove 124 extendingcircumferentially about the containment ring provides a recess forreceiving an elongate antenna or other device for providingcommunication with the instrument used to interrogate or communicatewith the data module carried in the receptacle 121 and groove 124.

In use, the containment ring 110 is threaded into position into thecenter location of a threaded coupling as indicated with the embodimentof FIGS. 1A-4. The threads 128 on the ring body 125 are adapted toengage the internal threads of the coupling to secure the ring to thecentral area of the coupling and hold it in place against axiallydirected displacement forces.

When the pipe ends are made up into the coupling, the ends of the pipeengage the end faces of the rims 126 and 127 if the pipe is advancedbeyond the J area dimension. The relative size of the boreholes 126 a,127 a and the axial dimensions of the rims 126, 127 as well as the axiallength of the body 125 cooperate so that the ring 110 may be crushed toa total axial dimension less than the spacing between the two pipe endswhen the pipe ends are at the penetration extremes of the tolerance fortheir API make up.

FIGS. 8-10 illustrate yet another modification of the containment ringof the present invention indicated generally at 210. The containmentring includes a receptacle 221 employed to receive and protect a radiotransmitter/receiver or other data module. An annular groove 224extending around a ring body 225 is employed to contain and protect anantenna or other functional component of the data module.

The containment ring 210 is provided with circumferentially extendingslots 226 a formed in one axial rim 226 of the ring body.Circumferentially extending slots 227 a are provided in the opposite rim227 of the containment ring. Threads 228 are provided along the centralexternal surface of the containment ring 210 for engagement with theinternal threads of the coupling with which the containment ring is tobe employed.

The alignment of the slots 226 a and 227 a is selected to provide acontrolled crushing resistance to the engagement of the ends of thecontainment ring by the ends of pipe being made up into a couplingcontaining the ring.

FIGS. 11-13 illustrate a modified form of the data resource of thepresent invention indicated generally by the containment ring 310. Theembodiment of FIGS. 11-13 is similar to the previously describedembodiment of FIGS. 8-10 with the exception that the circumferentialslots 326 a and 327 a are non-aligned. The result is that thecontainment ring 310 is less stiff than the ring 210 and may be moreeasily crushed by engagement of the ends of the pipe being made up intothe coupling within which the containment ring is positioned.

FIGS. 14-16 illustrate a modified form of the data resource of thepresent invention configured as a containment ring indicated generallyat 410. The containment ring 410 is similar to the containment ringspreviously described with the exception that the crush structure of thecontainment ring 410 is provided by bellows-type annular grooves in therims 426 and 427 of the containment ring. The bellows grooves areexemplified by the grooves 426 a, 426 b, 426 c and 426 d in the rim 426of the containment ring. When the ends of a pipe engage the rim 426 ofthe containment ring 410, the bellows grooves accommodate an axialcollapse of the rim 426 to prevent the containment ring 410 from beingdisplaced and to protect a data communicating device carried in thereceptacle 421.

FIGS. 17-19 illustrate a modified form of the data resource of thepresent invention embodied as a containment ring indicated generally at510. The containment ring 510 is similar to the containment ring 410illustrated in FIG. 14 with the exception that additional bellowsgrooves have been added to make the ring less stiff and thus more easilycollapsed.

FIG. 20 illustrates a modified form of the data resource of the presentinvention in the embodiment of a containment ring indicated generally at610. The containment ring 610 is similar to the rings 210 and 310illustrated previously with the exception that the circumferentiallyextending slots 626 a and 627 a are helically oriented and arecircumferentially aligned. The arrangement of the helical orientationand circumferential alignment provides a controlled crush resistance forthe containment ring 610. The difference in the crush resistance betweenthat of the previously described embodiments is employed for aparticular application requiring the controlled collapse of thecontainment ring with a specific coupling and pipe combination.

FIG. 23 illustrates a modified form of the data resource of the presentinvention indicated in the embodiment of a cemented electronic deviceindicated generally at 710. A transmitter or other electronic dataresource module 722, or other suitable information communicatingmechanism or device, is held in position along the center line of thecoupling 18 by a cement retention body 725. The body 725 is formed bythe applications of multiple successive coatings of an ultravioletactivated resin or a thermal setting resin such as Riton®, or othersuitable material. An antenna 723 comprises a part of the data moduleand is electrically secured to the communication device 722. The cementbody 725 extends axially less than one-half of the coupling J dimension.As thus deployed within the coupling 18, the data resource 710 isprotected from being crushed by the ends 11 and 12 of the pipes 13 and14 so long as the pipe is made up within API tolerance. The cement body725 may be made of any suitable material that is compatible with use ina well environment and functions to securely retain the device 722 andantenna 723 at the appropriate location within the metal coupling.

The information resource 710 is constructed within the coupling 18 byplacing the transmitter 722 along the center line of the coupling andapplying layers of the cement coating over the transmitter and antenna723. The cement bonds the transmitter and antenna to the internalthreaded surface of the coupling 18. The radial depth of the cement body725 may be approximately the same as the radial thickness of the pipemade up into the coupling to reduce turbulent flow through the pipe andcoupling.

FIG. 24 illustrates a form of the carrier ring of the present inventionindicated generally at 810 for use in a premium threaded coupling havinga central shoulder that is engaged by the ends of premium threaded pinsheld together by the coupling. It will be appreciated that the design ofFIG. 24 is also applicable to the box of integral joint pipe connectionsthat have the box formed integrally at the end of the pipe section,

The containment ring 810 is illustrated disposed within a dovetailgroove 818 a formed within a central shoulder 818 b formed internally ofa coupling 818. Pipe pins 813 and 814 are threadably received within thecoupling 818. the pin threads 816 and 817 and box threads such as 819are of a non API configuration sometimes referred to as premium threads.Proper makeup of the pin ends 813 and 814 with the coupling 818 requiresthe pin ends 811 and 812 to engage and bear against the internalshoulder

As best seen in FIG. 24A, the carrier ring 810 is provided with adovetail-shaped body 825. Placement of the carrier ring in the dovetailgroove protects the data resource from damage. The dovetail fit betweenthe body 825 of the carrier ring and the shoulder slot 818 a keeps thering locked in the slot. An antenna 824 for the date resource is carriedin a groove 825 a formed in the ring body 825. The carrier ring 810 isconstructed of a material with sufficient flexibility so that the ringbody 825 may be resiliently collapsed toward the groove 825 a as thering is inserted into the dovetail shoulder groove 818 a. Once thecompressed body 825 is received within the groove 818 a, the resiliencyof the body restores the ring to its fully expanded shape illustrated inFIG. 24.

FIGS. 25-27 illustrate a carrier ring indicated generally at 910employed for insertion into a dovetail cross-sectional groove formed inthe external shoulder of the premium threaded coupling. The ring 910 isconfigured as an annular ring body 925 having an annular internal groove924 formed along its outer circumferential surface. A data resource 22is deployed in a circumferentially extending recess formed in the body925 while a communications antenna 23 is deployed circumferentiallywithin the groove 924.

A radially reduced area or notch 925 a provided along the outercircumference of the body 925 allows the body to be temporarilycollapsed radially for insertion into the box groove.
